diffhub@0.1.13

Patch Changes

• 93966e1: Fix diffhub cmux hanging on "Loading diff…" or rendering empty panels. The cmux command was setting DIFFHUB_DISABLE_PRERENDER=1 whenever the server ran with a log file, which bypassed server-side prerender on every cmux session. When client-side rendering then hit a transient race (a stale poll arriving mid-fetch, or the dynamic PatchDiff import resolving into a section with content-visibility: auto), the user was left with no diff at all.

  Changes:

  • Stop disabling prerender just because the server has a log file; only disable when shiki's standalone module aliases are actually missing.
  • Log silent prerender failures instead of swallowing them, and time out individual prerenders after 3 s so one bad file can't block the whole response.
  • Re-queue the diff fetch if the only response in flight is dropped as stale; give up and reset state after three consecutive stale drops.
  • Abort and surface an error if /api/diff takes longer than 15 s, with a 5 s watchdog that offers an explicit Retry button instead of pulsing forever.
  • Wrap the PatchDiff render in a per-file error boundary so a malformed patch reports the error rather than leaving the panel blank.
  • Drop the per-file content-visibility: auto / contain-intrinsic-size: auto 300px wrapper that could keep newly rendered diffs hidden when their dynamic chunk resolved after the IntersectionObserver had already fired.
